AWS Lambda
less than a minute
AWS Lambda is a serverless computing platform provided by AWS, allowing developers to execute and scale their code in response to specific events without managing the underlying infrastructure.
By leveraging AWS Lambda, developers can build highly scalable, event-driven applications with minimal operational overhead.
Lambda supports multiple programming languages and integrates seamlessly with other AWS services.
It automatically provisions and manages the resources required to execute your code, handling scaling, patching, and capacity management.
Examples of AWS Lambda use cases include:
Image processing: Automatically resize, watermark, or compress images uploaded to an Amazon S3 bucket, optimizing them for faster load times and reduced storage costs.
Data processing: Perform real-time data transformation or filtering as data is ingested into AWS services, such as Kinesis Streams or DynamoDB, enabling efficient data analysis or storage.
Notifications: Send notifications or alerts to end-users via email, SMS, or push notifications when specific events occur, such as a new sign-up or a change in account status.
Scheduled tasks: Run periodic tasks, such as data cleaning or report generation, using CloudWatch Events or EventBridge to trigger Lambda functions on a schedule.
Serverless APIs: Build RESTful APIs using Amazon API Gateway, which integrates with AWS Lambda to execute the required logic, scaling automatically based on incoming traffic.
